Previous (Mar 15 - Mar 26)
- Some more simulations to get to the bottom of the energy gain puzzle. There have been some interesting ideas but no convincing solution yet.
- We made a fresh photocathode for the UITF gun to have enough juice for the optics studies that were planned for the remainder of the time before the upcoming shutdown. However,
there were mechanical problems during the transfer of the cathode into the gun. Joe ended up succeeding, but after half a day of beam operation, there was an arc in the gun, and
it is now making field emission to the point where it cannot be operated. Whether anything meaningful can be done before the shutdown is not clear yet.
- I had some discussions with Fu Ma about his simulation of the space charge issue in the pulsed cooling experiment. He is using simplified formulas for the field, which may be
good enough, but he is seeing an emittance increase without applying jitter, which we did not observe in our simulation. The reasons for that are yet to be determined.
Next (Mar 29 - Apr 9)
- UITF work depending on the course of action we decide on...
- Hoping to make some more improvements to JSPEC.

Previous two weeks (Mar 15 - Mar 26)
- Laser particle counter: continued literature search on micron sized particle delivery. Detector group has dismantled the current test setup and provided photos of the
setup before and after disassembly. Understanding previous data from the commercial (Wexx) particle counter to enable calibration of the prototype counters to be delivered.
Vendor anticipates several weeks of additional schedule delay due to underestimating effort needed to develop software for data acquisition and analysis, but is currently
implementing a new "acceleration" based algorithm for particle detection.
- Biweekly meeting with Omnisensing Photonics on detector prototype progress.
- Revisiting magnetized ion beam from magnetized ion sources to better understand current progress and limitations.
Next two weeks (Mar 29 - Apr 9)
- Continued literature review on coupled ion beams from magnetized ion sources. Work at FAIR describes using collimation to reduce the transverse emittance of the coupled beam,
collimating away over 50% of the beam in a bid to increase dimensionless beam brilliance. Working on setting up simulations in TRACK to work through A. Hutton's initial idea
of specific beam transforms to recover a round, uncoupled beam.
- Laser particle counter: Vendor anticipates delivery of 12 channel prototype detector towards the end of April - working to get a lab bench into the reserved space in the
Structures Lab in advance of the prototype delivery, and set up the existing test setup in the new space. Wexx particle counter data and manual indicate that the commercial
particle counter can measure particles up to about 3.6 um in diameter, which is somewhat useful for calibrating the new detector.
- Biweekly meeting with Omnisensing Photonics on detector prototype progress and delivery schedule.

Previous two weeks (Mar 15 - Mar 26)
- Isotopes: I met via BlueJeans with my REU student, Loida Rosado Del Rio, on Wednesday for the first time. She seems enthusiastic about working as the Editor on our next proposal. I also had a large meeting on Friday with our new collaborators from UVA and HU, Loida and our existing team from JLab and NMT, so that everyone could introduce themselves. I think we now have a powerful team and are much better placed to get funded. We will start attacking the proposal at the beginning of May when Loida officially starts. We are close to finalizing the 50 kW crucible design (Joe and Pavel Degtiarenko) to a level sufficient to close out the Milestone for our existing proposal. This will be “recycled” as input to the new proposal. This week, I will start preparing the APS talk that will be given by Steve.
- ERLs: This is proceeding smoothly. I have asked several JLab staff members for short write-ups and have got positive answers from all - including George Neil even though he is retired! Max presented our input to the European Lab Directors Group and it was well received. We will need to organize a public meeting sometime this summer.
- PERLE: No news is not necessarily good news
- New Accelerator Facility - no response from Stuart or Andrei, so I am moving forward. I have a meeting with the Business Development Manager for Advanced Technologies at BWX
Technologies, Inc. this afternoon to explore areas where we might collaborate.
Next two weeks (Mar 29 - Apr 9)
- Isotopes: I spent time preparing a talk that Steve will present at the APS April Meeting. For this, I started to try and lock down our production numbers and had
several meetings about it. It is still not so clear! I had an excellent talk with Ethan Balkin. our Program Manager, and sent the noted already. Since the Isotope Program
will not have an FOA before this summer (and we don’t know what form it will take) I have started looking into other funding sources. There may be a possibility of seeking
SBIR funds, I have feelers out! Lila will finish up her program on decay modes of all of the isotopes and will publish that at IPAC’21. She will not have time to complete
the other part of the program, the daughter isotopes produced when a 𝛾, n, p,d,or 𝛼 strike the mother. I have changed Loida’s project to complete this part of the program,
and then have Lila and Loida publish the final result together. There was an excellent article on gallium in Physics Today by Michael Dickey at North Carolina State in
Raleigh. I contacted him and will be talking with him next week. I think he will be an excellent collaborator if I can talk him into joining us.
- ERLS: The panel met and we have assigned writing tasks, most have accepted. The timeline is to produce a very first draft in May so that there can be an “community meeting" in June to present the rough vision and seek input. This has to happen before the CERN SPC on June 22,23 and the CERN Council meeting June 26. So that will be a fair amount of work over the next couple of months.
- PERLE: I contacted Jean-Luc Biarrotte directly, in French, and actually got a response. Their marked up copy of the ICRADA was delivered, I forwarded it to Rhonda who has contacted me about her comments, and I think it is close to going up to the DOE again - I think! .
